Risa Sargent

Biography

Dr. Sargent studies the evolutionary ecology of flowering plants and their predators and pollinators. Research in her lab is focused on the influence of pollinators on floral trait evolution and plant community assembly; pollinator-mediated interactions between invasives and natives; the potential for invasive plant species to evolve in response to biological control agents; and the effects of disturbances on pollinator communities and plant reproduction.
